CVE-2026-9617— PostgreSQL Anonymizer: malicious column name allows SQL injection via anon.k_anonymity() function

PostgreSQL Anonymizer: malicious column name allows SQL injection via anon.k_anonymity() function

PostgreSQL Anonymizer contains a vulnerability that allows a user to gain superuser privileges by creating a table and placing malicious code inside a column identifier. If a superuser calls the k-anonymity function, the malicious code is executed with superuser privileges. The risk is higher with PostgreSQL 14 or with instances upgraded from PostgreSQL 14 or a prior version. With PostgreSQL 15 and later, the creation permission on the public schema is revoked by default and this exploit can only be achieved by a user who was explicitly granted the CREATE TABLE privilege. The problem is resolved in PostgreSQL Anonymizer 3.1.0 and further versions

PostgreSQL Anonymizer 安全漏洞

PostgreSQL Anonymizer是法国DALIBO开源的一个用于屏蔽或替换 PostgreSQL 数据库中的个人身份信息 (PII) 或商业敏感数据的扩展软件。 PostgreSQL Anonymizer存在安全漏洞，该漏洞源于允许用户通过创建表并在列标识符中放置恶意代码来获得超级用户权限，可能导致超级用户调用k-anonymity函数时执行恶意代码。
